They are in the Marine 5 tons, and in my experience, the ones in service suffered alot of worn out and or broken transfer cases, I would do it in a heart beat if I could afford it though, That is just something i have noticed, more marine 5 tons with bad transfer cases than Army issue, That I have seen over the years, there is ALOT more work being done to the drive train, But they have a purpose, if its going to be used in parades and displays the lockers are not such a good idea, but its up to the owner...I have driven one around for a year with lockers a Marine 5 ton, and man they tear up the earth when turning, very very cool....

...Oh and the transfer was smoked in it when i got it also, That was work for sure...
